DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a water heater employing the control device according to the present invention will be described below with reference to the drawings.

(Embodiment 1) FIG. 1 shows a water heater according to an embodiment of the present invention. First, automatic hot water supply and reheating which are performed during normal operation will be described. When the switch 31 for automatic hot water supply is pressed, water is supplied from the water inlet, passes through the water quantity sensor 1 and the hot water supply water thermistor 2 which are water quantity detecting devices, and absorbs heat by the heat exchanger 3 for hot water supply to become hot water. The hot water becomes a constant amount of water after passing through the hot water supply and hot water discharge thermistor 4, and the temperature detected by the hot water supply and hot water discharge thermistor 4 becomes the temperature set by the bath temperature setting knob 29 which is a bath temperature setting means. 16 is adjusted and adjusted. Then, the hot water that has passed through the automatic hot water supply solenoid valve 6 is passed through the check valve 7, the bath water flow switch 8, the bath thermistor 9, the heat exchanger 10 for the bath, and the reheating door to the bathtub 12 via the bath adapter 11. And so on. When the two-way valve 13 opens during the sequence (there are two states of "open" and "closed"), the reheating outlet also flows into the bathtub 12. This hot water is supplied by an automatic hot water supply amount setting knob 3 which is an automatic hot water supply amount setting means
The hot water is supplied up to the set amount set by 0, and the operation of the automatic hot water supply ends. In addition, the gas reaches the original solenoid valves 14 and 15, the proportional valves 16 and 17 and the burners 18 and 19 which are supply heat amount adjusting devices from the upstream of the hot water supply side and the bath side respectively. Combustion blowers 20 and 21 are provided below the heat exchangers 3 and 10, respectively.

When the operation of the automatic hot water supply is finished and the reheating switch 32 is pushed, the two-way valve 13 is fixed to "open",
The circulation pump 22 is started. The hot water sucked up from the bathtub 12 through the reheating and returning port is the bath water flow switch 8,
It flows through the bath thermistor 9 and the bath heat exchanger 10, and further absorbs heat and returns to the bathtub 12 through the reheating port. Then, when the temperature of the hot water in the bathtub 12 detected by the bath thermistor 9 reaches plus 2 ° C. of the temperature set by the bath temperature setting knob 29, the combustion is stopped and the trial operation for reheating is completed. At this time, the check valve 7 does not flow toward the automatic hot water supply solenoid valve 6.

The above is the abnormal operation. Then, the trial operation mode will be described below. When performing the trial run mode, the trial run connector 24 on the electrical component unit 23 is used.
Pin (first in normal operation connector 25)
Insert 24a. Then, the same operation as the normal automatic hot water supply starts. However, what is different here is that, first of all, the amount of hot water supplied to the bathtub 12 is smaller than the minimum amount of the normal set hot water supply. As shown in FIG. 2, the hot water supply amount is almost just above the bath adapter 11. This is the minimum amount of water that can be reheated afterwards, and this amount of water is the amount of water B, and the minimum amount of water of the hot water supply amount setting means is the amount of water A, that is, the difference (water amount A-water amount B) is improved in operability ( Shortening of hot water supply time, reduction of water and gas consumption) can be obtained.
Another difference is that the hot water supply temperature is set to, for example, plus 2 ° C. of the incoming water temperature, and the gas consumption amount can be reduced by suppressing this set temperature. When the trial operation of the automatic hot water supply is completed in this way, the trial operation of the additional heating operation is automatically started according to the trial operation program. The operation of the reheating operation itself is the same as usual, but the difference here is that the rising temperature of the reheating operation is fixed at, for example, plus 2 ° C. without the bath temperature setting means working. Circulation pump 22
When the circulatory movement starts, the bath thermistor 9 first detects and stores the temperature of the hot water in the bath tub 12. Based on that data, if the temperature rises to + 2 ° C, the combustion will be stopped and the trial run for reheating will be completed.

Upon completion of these two trial runs, the trial run mode of the equipment is finished, and the display section 28 displays "End of trial run". In addition, a display may be attached to prompt the user to "return the pin to the normal operation mode" so that the trial operation mode returns to the original normal operation mode. A simple flowchart of the above description is shown in FIG. (I) shows the contents of each program for automatic hot water supply and (II) for reheating.

(Embodiment 2) In order to carry out the test operation mode, in the embodiment 1, a means for inserting the pin 24a into the test operation connector 24 on the electrical equipment unit 23 is adopted. However, with this method, the front cover (not shown) of the equipment had to be purposefully opened, and at the same time, it was difficult to see the state of the trial run (because the bathtub 12 and the equipment are separated). Therefore bath controller 2
A switch for trial operation (not shown) is newly provided on 7 and the trial operation mode is set by pressing the switch. This is the basic circuit configuration of pin 2
4a. However, it may be considered that the switch is moved from the electrical equipment unit 23 to the bath controller 27.

(Embodiment 3) However, in Embodiment 2, since the operation is simple, there is a drawback that a general user mistakenly uses it. Therefore, only the enforcer can operate it easily, and the existing switches are pushed multiple times in hidden mode so that ordinary users do not know how to operate. For example, the automatic hot water supply switch 31, the reheating switch 32, and the operation switch 33 on the bath controller 27 may be simultaneously pressed. The display of "completion of trial run" at the end of the trial run mode should be canceled by pressing any switch thereafter. A simple circuit configuration diagram of this embodiment is shown in FIG.

According to each of the above-described embodiments, the test operation for automatic hot water supply or reheating can be performed by a simple operation such as multiple pressing of the pin 24a, the switch for the test operation, or the existing switch, and the efficiency of the test operation work can be improved. Get better. In addition, when the test run program is wide-ranging, it is possible to eliminate work errors due to complication of the test run, and it is possible to expect accurate work in addition to improvement in efficiency.

[0020]

As is apparent from the above description, the control device according to the first aspect of the present invention is useful for improving the work efficiency of the trial run.

The control device according to claim 2 can be expected to perform a trial operation by a simple operation, and the control device according to claim 3 can be operated only by the operator, and a new switch or circuit is not added. There is an effect that you may.
